Perfluorinated carboxylic acids (PFCAs), including perfluorooctanoic acid (PFOA), are persistent organic pollutants that pose human health risks. However, sources of contamination and exposure pathways of PFCAs have not been explored. In this study, PFCA concentrations were quantified in personal care products. Among 24 samples that listed fluorinated compounds, such as polyfluoroalkyl phosphate esters (PAPs), in their international nomenclature of cosmetic ingredients (INCI) labels, 21contained PFCAs (13 of 15 cosmetic samples, and 8 of 9 sunscreen samples). The concentrations of total PFCAs ranged from not detected to 5.9 μg g(-1) for cosmetics and from not detected to 19 μg g(-1) for sunscreens. We also investigated components of PFCAs in cosmetics and sunscreens. Commercially available compounding agents, mica and talc, which were treated with PAPs were analyzed and high concentrations of PFCAs were detected (total PFCAs 2.5 μg g(-1) for talc treated with PAPs, 35.0 μg g(-1) for mica treated with PAPs). To the best of our knowledge, this is the first report on contamination of end consumer products containing PAPs with high concentrations of PFCAs.
全氟羧酸（PFCAs），包括全氟辛酸（PFOA），是持久性有机污染物，对人类健康构成威胁。然而，其污染来源和暴露途径尚未得到探索。在这项研究中，对个人护理产品中的 PFCAs 浓度进行了量化。在其国际化妆品成分命名（INCI）标签中列出了含氟化合物（如多氟烷基磷酸酯（PAPs）的 24 个样本中，有 21 个样本含有 PFCAs（15 个化妆品样本中有 13 个，9 个防晒霜样本中有 8 个）。化妆品中总 PFCAs 的浓度范围为未检出至 5.9μg/g，防晒霜中总 PFCAs 的浓度范围为未检出至 19μg/g。我们还研究了化妆品和防晒霜中 PFCAs 的成分。经过 PAPs 处理的商业上可获得的复合剂云母和滑石粉进行了分析，发现其中含有高浓度的 PFCAs（经过 PAPs 处理的滑石粉中总 PFCAs 为 2.5μg/g，经过 PAPs 处理的云母中总 PFCAs 为 35.0μg/g）。据我们所知，这是首次报道含有 PAPs 的终端消费产品被高浓度 PFCAs 污染。
